SAFETY NIPPLE Application led .Tune- 15,

This invention relates generally to a babys bottle, and has moreparticular reference to a novel nipple therefor.

The invention has for an object the pros vision of a device of the classmentioned, which is of simple durable construction, de-

sirable and efcent in action, and which can be manufactured and sold ata reasonable cost.

The invention proposes the use of a nipple having a stopper portion forinsertion into the mouth of a babys bottle, and a flange portionarranged for engaging over and disengaging from the neck of the saidbottle. In its normal disengaged position the flange is directedupwardly and around the main portion of the nipple, and it may be turneddownwards for engaging the neck of the babys bottle.

One of the main advantages of this arrangement is that the nipple isfirmly held in place on a babys bottle by reason of the stopper and theflange, this obtaining a posi* tive and reliable connection. In additionleaking of milk from the bottle is highly improbable due to theroundabout path necessary to travel for leaking. First the milk wouldhave to pass along one direction and along the stopper,-and then in theopposite 3o direction and along the flange.

For further comprehension of the invention, and of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawings and to the appended claims in which thevarious novel features of the invention are more particularly set forth.

In the accompanying drawing, formingv a 0 material part of thisdisclosure:

1928. Serial No. 285,665.

'tion 14 of a nipple having a main body 15 and an integral flange 16arranged for engaging over the neck 12, or for being turned upwards asshown by the dot-dash lines 17 in Fig. 2, and by full. lines in Fig. 3.The stopper portion 14 is formed with an aperture Y18 provided with aflexible tubular projection 14 adapted to receive one end of a tube 19which extends to a small distance from the bottom of the bottle 10.

When the bottle is laid on its side, the end of the tube 19 near to thebottom of the bottle 10 hangs down toward the lower edge of the bottle,thereby allowing most of the milk to be sucked out of the bottle.

In applying the nipple on a bottle, the flange 16 should be turned intoraised position, and then the, stopper 14 forced into the mouth of thebottle. Next the flange 16 should be turned down over the neck of thebottle.

Suitable air holes 15 are provided in the nipple preferably near thestopper portion 14.

InFigs. 4, 5 and 6, the tube 19 is climi.- nated from the device, andthe flange 16 is formed with a groove 20 for engagement over theenlarged end 13, and with a bulge 21 for engagement against the side ofthe neck 12. This organization provides a finer fit of the nipple uponthe bottle, and acts for further insuring against milk leakage from thebottle. In Fig. 7 small integral fla s 22 are shown connected on theflange 16 or providing a gripping element for raising and lowering theflange.

The modified form shown in Fig. 8, discloses a comparative non-elasticflange 24, 100

relative to the material of the nipple, such as rubberized cloth,secured to the top of the stopper 14 by reason of having its ends castinto the stopper, and arranged for engaging over the neck 12 of thebottle. The fiange 16 engages over the flange 24, when turned downwardsfor forcinflI the flange 24 firmly against the neck 12. This arrangementalso prevents leakage of milk froml engaging against the ange 16.

. While I have shown and described the preferred embodiment of myinvention, it is to be understood that I do not limit myself to theprecise construction herein disclosed and the right is reserved to allchanges and modifications coming within the scope ofthe invention asdefined in the appended claims.

Having thus described my invention, what I claim as new and desire tosecure by United States Letters Patent is:

1. A nipple for a babys bottle having a neck with an enlarged top edge,and a mouth, comprising a main portion, a stopper portion integraltherewith and engageable in the said mouth, an integral fiangecngageable over the neck of the bottle, and a comparative nonelasticfiange attached to the stopper and engageable over the neck of thebottlel beneath the said flange.

2. A nipple for a babys bottle havinga neck with an enlarged top edge,and a mouth, comprising a main portion, a stopper portion integraltherewith and cngageable in the said mouth, an integral flangeengageable over the neck of the bottle, and a comparative nonelasticflange attached to the stopper by reason of having its edges cast intothe material of the stopper and cngageable over the neck of the bottlebeneath the said fiange.

3. A nipple for a babys bottle having a neck with an enlarged top edge,and a mouth, comprising a main portion, a stopper portion integraltherewith and cngageable in the said mouth, an integral flangeengageablev over the neck of the bottle, and a comparative rubberizedcloth flange attached to the stopper and engageable over the neck rofthe bottle beneath the said flange.

In testimonyr whereof I have aiiixed my signature.
